Something I really miss from other DAWs is smart disable of effects to save on CPU. On my laptop i can run out of real-time CPU quickly.
This feature would include:
Audio detection-based disabling of plugins in the style of FL Studio - when the channel is silent or drops below a certain level, the DAW automatically disables the effects freeing up CPU. A selectable threshold would be nice too.
An per-channel (or global) option to automatically disable all plug-ins on the mute of a channel, as happens in REAPER. This can cause a delay when un-muting, but having the option would be great for high-cpu effect racks.
This whole feature would be very useful for people working on non-optimal systems, which is probably most users.
At the moment, one can be running with muted or silent channels hogging vast amounts of CPU
